SUPPLEMENTARY INFORMATION:
Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Airbus Canada
Limited Partnership Model BD-500-1A10 airplanes. The NPRM published in
the Federal Register on December 6, 2022 (87 FR 74522). The NPRM was
prompted by AD CF-2022-51, dated August 30, 2022 (Transport Canada AD
CF-2022-51), issued by Transport Canada, which is the aviation
authority for Canada (also referred to as the MCAI). The MCAI states
certain airplanes may have entered service with the OWEED escape line
incorrectly routed, in a manner that would render it inoperable when
needed. The OWEED escape line is used to facilitate passenger egress
along the wings following a ditching event. It is possible for the
OWEED escape line to be installed under the liner of the OWEED
resulting in the escape line not deploying, which could cause possible
injuries to passengers escaping over the wing following a ditching
event.
In the NPRM, the FAA proposed to require inspecting the OWEED
escape line and correcting the routing if required, as specified in
Transport Canada AD CF-2022-51. The FAA is issuing this AD to address
he unsafe condition on these products.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2022-1492.

Discussion of Final Airworthiness Directive
Comments
The FAA received a comment from Air Line Pilots Association,
International (ALPA) who supported the NPRM without change.
The FAA received an additional comment from one commenter, Delta
Air Lines (Delta). The following presents the comment received on the
NPRM and the FAA's response to each comment.
Request for Correction of Service Bulletin
Delta commented that step 2.3.4 in the Accomplishment Instructions
of Airbus Canada Limited Partnership Service Bulletin BD500-256005
Issue 001 dated 14 April 2020, contains a typographical error. Delta
noted that step 2.3.4 states ``Torque the screws (2) to 25 to 30
lbf[middot]in. (2.82 to 3.39 Nm) (refer to AMP BD500-A-J20-31-00-00AAA-
711A-A).'' Delta stated that Airbus Canada confirmed that the ``(2)''
reference is incorrect and should be ``(1).'' Delta added that ``screws
(2)'' do not exist and are not identified in any other step or figure
in Airbus Canada Limited Partnership Service Bulletin BD500-256005
Issue 001 dated 14 April 2020.
The FAA agrees and confirmed with Airbus Canada Limited Partnership
that this is a typographical error and the correct reference in step
2.3.4 is ``(1).'' The FAA added paragraph (h)(2) to this AD to allow
using the correct reference for the step.
Conclusion
This product has been approved by the aviation authority of another
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI
referenced above. The FAA reviewed the relevant data, considered the
comments received, and determined that air safety requires adopting
this AD as proposed. Accordingly, the FAA is issuing this AD to address
the unsafe condition on this product. Except for minor editorial
changes, and any other changes described previously, this AD is adopted
as proposed in the NPRM. None of the changes will increase the economic
burden on any operator.
Related Service Information Under 1 CFR Part 51
Transport Canada AD CF-2022-51 specifies procedures for doing a
detailed inspection of the OWEED escape line routing and correcting the
OWEED escape line routing, if required. This material is reasonably
available because the interested parties have access to it through
their normal course of business or by the means identified in ADDRESSES
section.
Costs of Compliance
The FAA estimates that this AD affects 4 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
1.5 work-hours x $85 per hour = $128......................... $0 $128 $512
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition action that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need this on-condition action:
Estimated Costs of On-Condition Actions
----------------------------------------------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.............................................. $0 $85
----------------------------------------------------------------------------------------------------------------
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
Under that section, Congress charges the FAA with promoting safe flight
of civil aircraft in air commerce by prescribing regulations for
practices, methods, and procedures the Administrator finds necessary
for safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.
Regulatory Findings
This AD will not have federalism implications under Executive Order
13132. This AD will not have a substantial direct effect on the States,
on the relationship between the national government and the States, or
on the distribution of power and responsibilities among the various
levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
